Hexologic: Chained logic sums

GAME INFO
Hexologic, chained logical sums, is the online maths and logic game for children and adults. Click on the hexagons to change the number of points, thus the number that each hexagon represents. Modify the numbers so that the lines of hexagons add up to the number e indicated, bearing in mind that the hexagons are part of chained sums, i.e. the hexagons are part of several sums at the same time. Solve hexologic problems with hexagons using the logics in simple but related sums.
